Did I text sensitive information to a stranger?

I have an iPhone that is connected to sprint, I've had 3 different numbers, the one I have and the 2 I had before.
Today I asked my friend to text me very sensitive information. I waited awhile and never got the text. I saw that she still had my very first number from a year ago. Since they were both iPhones I could see that the message was read?! But it wasn't sent to me. Who read the message that was sent to my old phone number? So I looked up the number in OkCaller dot com and it came up as the owner being me. My name popped up. So we called it but it only rang twice and went straight to voice mail. It wasn't only that time, we called through out the day with 6 different phones and with every phone it always went to voice mail after ringing twice.

Is it a number still under our contract that just isn't activated? Did a stranger get my old number? Because the message went from "delivered" to "read".

Which iPhone 5c should I get?

How to make use of Snapchat?

I prefer to use Snapchat on the iPhone. Snapchat is not available in the Finnish language. I can't use it in French in the United States. I'm horrible at the technology. I know basic skills in school, but I do not do well most of in my classes, except for those who teach the arts, but I'm not smart.

I can't use Snapchat in French when my iPhone is set in Finnish. I live in the American region, so nothing is available to me.

Added (1). The Americans say, "Get out of California and go to France or Canada, or just go back to Finland." But I love living in America.

PC won't recognize my iPhone. Tried everything?

I recently got an iPhone 6S, but my PC won't recognize it. It comes up as "Apple iPhone" but with a weird picture, rather than an icon of an iphone, and lets me open photos and videos only. ITunes won't recognize my phoen at all so I can't sync my music. I know it's my laptop because my friend s iPhone came up the same and my phone worked with a different laptop. I've tried different USB cables, reinstalling iTunes, updating Windows and iTunes, restarting my PC and phone, troubleshooting. Absolutely nothing works. Can't find anything on the internet that I haven't tried.

Are iPhone users brainwashed?

I see people buying iPhone without even looking at the competition, they might find a product better suited for their needs, easier to use, and discover features they didn't know they would like. But Apple brainwashed them to convince them "anything else won't work good", "anything else won't sync", "anything else will be to hard to use", "convincing them they can't switch and keep their data", "convincing them anything else want sync up with their Mac" "other phones get virus(iphone get virus)", you don't get updates fast(Nexus get updates the same day) etc.

iPhone isn't the only phone that video call, messages, syncs, fast and easy to use. It not even very durable. Compared to the competition iPhone has dated technology, and everything iPhone users like companies like Samsung do or already done better for the same price. Like storage, battery life, charge time etc. Apple doesn't innovate, I seen phones with shatterproof screens, waterproof, 3d screens, quad hd, 4k and oled displays. Fast charging, wireless charging, heart rate monitor, stylus, dual cameras, split screens, NFC and bluetooth sharing, VR headset etc, there's a lot more.

I mean at least Look at something else

Extension cord makes my charger hot?

Why does the indoor extension chord make my phone charger hot? It's an iPhone 6 charger. Whenever I have it plugged in the extension cord it gets hot to the point it's burning hot to the touch. I've tried changing chargers and extension chords but it still does this.
